I kept this piece of trash for my grandchildren to break. It's likely made from 100% plastic and makes terrible noises when you pull the handle. The mechanism is also plastic therefore doesn't require too much pressure to make the wheels spin. I had hoped it would do more. I complained and received a partial refund. Returning was too expensive.  I cannot recommend this product. It will likely break in a short while. This purchase taught me to be more cautious when making a purchase. It's only plus it Gers is for entertainment and that likely won't last long.
